Hoplites were citizen-soldiers of Ancient Greek city-states who were primarily armed with spears and shields. Hoplite soldiers used the phalanx formation to be effective in war with fewer soldiers. The formation discouraged the soldiers from acting alone, for this would compromise the formation and minimize its strengths. The hoplites were primarily represented by free citizens – propertied farmers and artisans – who were able to afford a linen or bronze armour suit and weapons. They also appear in the stories of Homer, but it is thought that their use began in earnest around the 7th century BC, when weapons became cheap during the Iron Age and ordinary citizens were able to provide their own weapons. Most hoplites were not professional soldiers and often lacked sufficient military training. Some states maintained a small elite professional unit, known as the epilektoi or logades since they were picked from the regular citizen infantry. These existed at times in Athens, Sparta, Argos, Thebes, and Syracuse, among other places. Hoplite soldiers made up the bulk of ancient Greek armies.
The Roman legion, the largest military unit of the Roman army, was composed of Roman citizens serving as legionaries. During the Roman Republic the manipular legion comprised 4,200 infantry and 300 cavalry. After the Marian reforms in 107 BC the legions were formed of 5,200 men and were restructured around 10 cohorts, the first cohort being double strength. This structure persisted throughout the Principate and middle Empire, before further changes in the fourth century resulted in new formations of around 1,000 men.
The pilum was a javelin commonly used by the Roman army in ancient times. It was generally about 2 m long overall, consisting of an iron shank about 7 mm (0.28 in) in diameter and 600 mm (24 in) long with a pyramidal head, attached to a wooden shaft by either a socket or a flat tang.
The Praetorian Guard was an elite unit of the Imperial Roman army that served as personal bodyguards and intelligence agents for the Roman emperors.
The Roman legionary was a citizen soldier of the Roman army. These soldiers would conquer and defend the territories of ancient Rome during the late Republic and Principate eras, alongside auxiliary and cavalry detachments. At its height, Roman legionaries were viewed as the foremost fighting force in the Roman world, with commentators such as Vegetius praising their fighting effectiveness centuries after the classical Roman legionary disappeared.
A cohort was a standard tactical military unit of a Roman legion. Although the standard size changed with time and situation, it was generally composed of 480 soldiers. A cohort is considered to be the equivalent of a modern military battalion. The cohort replaced the maniple. From the late second century BC and until the middle of the third century AD, ten cohorts made up a legion. Cohorts were named "first cohort", "second cohort", etc. The first cohort consisted of experienced legionaries, while the legionaries in the tenth cohort were less experienced.
The Roman army was the armed forces deployed by the Romans throughout the duration of Ancient Rome, from the Roman Kingdom to the Roman Republic and the Roman Empire, and its medieval continuation, the Eastern Roman Empire. It is thus a term that may span approximately 2,206 years, during which the Roman armed forces underwent numerous permutations in size, composition, organisation, equipment and tactics, while conserving a core of lasting traditions.
Ancient warfare is war that was conducted from the beginning of recorded history to the end of the ancient period. The difference between prehistoric and ancient warfare is more organization oriented than technology oriented. The development of first city-states, and then empires, allowed warfare to change dramatically. Beginning in Mesopotamia, states produced sufficient agricultural surplus. This allowed full-time ruling elites and military commanders to emerge. While the bulk of military forces were still farmers, the society could portion off each year. Thus, organized armies developed for the first time. These new armies were able to help states grow in size and become increasingly centralized.
The scutum was a type of shield used among Italic peoples in antiquity, most notably by the army of ancient Rome starting about the fourth century BC.
In the Roman army during classical antiquity, a centurion, was a commander, nominally of a century, a military unit originally consisting of 100 legionaries. The size of the century changed over time; from the 1st century BC through most of the imperial era it was reduced to 80 men.
The phalanx was a rectangular mass military formation, usually composed entirely of heavy infantry armed with spears, pikes, sarissas, or similar polearms tightly packed together. The term is particularly used to describe the use of this formation in ancient Greek warfare, although the ancient Greek writers used it to also describe any massed infantry formation, regardless of its equipment. Arrian uses the term in his Array against the Alans when he refers to his legions. In Greek texts, the phalanx may be deployed for battle, on the march, or even camped, thus describing the mass of infantry or cavalry that would deploy in line during battle. They marched forward as one entity.
A vexillatio was a detachment of a Roman legion formed as a temporary task force created by the Roman army of the Principate. It was named from the standard carried by legionary detachments, the vexillum, which bore the emblem and name of the parent legion.
Roman military personal equipment was produced in large numbers to established patterns, and used in an established manner. These standard patterns and uses were called the res militaris or disciplina. Its regular practice during the Roman Republic and Roman Empire led to military excellence and victory. The equipment gave the Romans a very distinct advantage over their barbarian enemies, especially so in the case of armour. This does not mean that every Roman soldier had better equipment than the richer men among his opponents. Roman equipment was not of a better quality than that used by the majority of Rome's adversaries. Other historians and writers have stated that the Roman army's need for large quantities of "mass produced" equipment after the so-called "Marian Reforms" and subsequent civil wars led to a decline in the quality of Roman equipment compared to the earlier Republican era:
The production of these kinds of helmets of Italic tradition decreased in quality because of the demands of equipping huge armies, especially during civil wars...The bad quality of these helmets is recorded by the sources describing how sometimes they were covered by wicker protections, like those of Pompeius' soldiers during the siege of Dyrrachium in 48 BC, which were seriously damaged by the missiles of Caesar's slingers and archers.
It would appear that armour quality suffered at times when mass production methods were being used to meet the increased demand which was very high the reduced size cuirasses would also have been quicker and cheaper to produce, which may have been a deciding factor at times of financial crisis, or where large bodies of men were required to be mobilized at short notice, possibly reflected in the poor-quality, mass produced iron helmets of Imperial Italic type C, as found, for example, in the River Po at Cremona, associated with the Civil Wars of AD 69 AD; Russell Robinson, 1975, 67
Up until then, the quality of helmets had been fairly consistent and the bowls well decorated and finished. However, after the Marian Reforms, with their resultant influx of the poorest citizens into the army, there must inevitably have been a massive demand for cheaper equipment, a situation which can only have been exacerbated by the Civil Wars...
A javelin is a light spear designed primarily to be thrown, historically as a ranged weapon. Today, the javelin is predominantly used for sporting purposes such as the javelin throw. The javelin is nearly always thrown by hand, unlike the sling, bow, and crossbow, which launch projectiles with the aid of a hand-held mechanism. However, devices do exist to assist the javelin thrower in achieving greater distances, such as spear-throwers or the amentum.
Heavy infantry consisted of heavily armed and armoured infantrymen who were trained to mount frontal assaults and/or anchor the defensive center of a battle line. This differentiated them from light infantry who were relatively mobile and lightly armoured skirmisher troops intended for screening, scouting, and other tactical roles unsuited to soldiers carrying heavier loads. Heavy infantry typically made use of dense battlefield formations, such as shield wall or phalanx, multiplying their effective weight of arms with force concentration.
The Imperial Roman Army was the military land force of the Roman Empire from 27 BC to 476 AD, and the final incarnation in the long history of the Roman army. This period is sometimes split into the Principate and the Dominate (284–476) periods.
The Roman army of the late Republic refers to the armed forces deployed by the late Roman Republic, from the beginning of the first century BC until the establishment of the Imperial Roman army by Augustus in 30 BC.
Roman infantry tactics are the theoretical and historical deployment, formation, and manoeuvres of the Roman infantry from the start of the Roman Republic to the fall of the Western Roman Empire. The focus below is primarily on Roman tactics: the "how" of their approach to battle, and how it stacked up against a variety of opponents over time. It does not attempt detailed coverage of things like army structure or equipment. Various battles are summarized to illustrate Roman methods with links to detailed articles on individual encounters.
